[xwiki-users] HTTP status 500 - xwiki entreprise 7.1.2 on RHEL6/MySql

29 Aug 2015

      Hello,

After a lot of tests on a debian version (where « everything »  is made for
us), i would like to implement the 7.1.2 of wiki enterprise to a dev
environment following my company actual "standard ». I hope, after some
time and tests, push this into production.

The base system is composed by :

- RHEL 6.7
- MySQL
- Tomcat6
- openjdk 7

I have followed the installation guide to configure everything as i think
it must be.

But at first launch of xwiki, i have obtained an « HTTP STATUS 500 » with
the wall of text below.

This is the adapted part ot he hibernate.cfg.xml file related to MySQL if
needed :

<!-- MySQL configuration.
         Uncomment if you want to use MySQL and comment out other database
configurations.
         Notes:
           - if you want the main wiki database to be different than "xwiki"
             you will also have to set the property xwiki.db in xwiki.cfg
file
    -->
    <property name="connection.url">jdbc:mysql://localhost/xwiki</property>
    <property name="connection.username">xwiki</property>
    <property name="connection.password">xwiki</property>
    <property
name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property
name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    <property name="connection.useUnicode">true</property>
    <property name="connection.characterEncoding">UTF-8</property>
    <property name="dbcp.poolPreparedStatements">true</property>
    <property name="dbcp.maxOpenPreparedStatements">20</property>
    <mapping resource="xwiki.hbm.xml"/>
    <mapping resource="feeds.hbm.xml"/>
    <mapping resource="activitystream.hbm.xml"/>
    <mapping resource="instance.hbm.xml"/>
    <mapping resource="mailsender.hbm.xml"/>

I have first tested the "7.2-Milestone 2 » version. I have seen some error
like this one with other people and the milestone 3, with apparently
correction to their errors, is not already available as a war file. So I
have switched back to the the stable version. Same error…

Could you please point me to the right direction with this ?

Thanks

Daniel.
